Any news?
Yes, it is much more upsetting having to see it happen "live". On the other hand, the small silver lining is that it gives a tiny chance to the people who can save her. If it happens in a dark room, nobody will know about it until it's all over.
It might be a good idea to look at the possibilities of counseling for everyone who happened to see that. Suicide is crushing enough, and having to watch it/not knowing it will be OK is more than most can humanly bear. Some might be in shock and develop a trauma from this. I don't know if there are orgs who work in this field near you, but I suspect there are. Please do call them and ask for help.
